CAPACITORS
10.Jan.2023
INTRODUCTION
The capacitor is a simple passive component used to “save electricity”. If we connect it via DC power source, the capacitor will accumulate the charge, which then remains for a while, even after we have turned the source off. The simplest, it works as a small rechargeable battery. Very small, because the charge is quickly discharged or charged. This process can be limited by a series of resistors which allows using the capacitor as a timing component in smaller electric circuits. The capacitor can also be used for blocking DC which pulsates, eliminating “noises”, as well as “ironing” audio or other wave signals.
HOW DOES IT WORK?
The majority of capacitors consists of two conductive plates, mutually separated by some dielectric material. These are the materials that require great energy to conduct electricity, which is practically impossible. Boards themselves are built of thin metal sheets, most commonly rolled into a cylinder in order to minimize the size of a component.
